I mean, as it says at the end, this blog post is in good fun. It most definitely expresses frustration, but it also recognizes that perfect is the enemy of good, and that you already put in more effort than one can expect by writing a tutorial to begin with.

I guess, my main takeaway is that you really don’t need to bother writing up your life story. It will fly over the head of your readers, for sure. (Although a bit of context may still be important.)
And you should probably spend a few more words, describing the actual steps, no matter how obvious those may seem to you.
